Embodiment 1
[0038] A solid polymer electrolyte membrane material with continuous ion-transfer nanochannels, which is a comb copolymer (molecular weight of 5,000 to 20,000, wherein The MPEG content is 30wt%, and the relative molecular weight of MPEG is 350). The micelles formed by self-assembly are fused with lithium salt, and the film formed by cross-linking; wherein the micelles are spherical or ellipsoidal in shape, and the size range is about 50nm-500nm.
[0039] The above-mentioned preparation method of the solid polymer electrolyte membrane material with continuous ion transfer nanochannels, the steps are as follows:
[0040] (1) Accurately weigh 0.05g PCOE-g-MPEG (MPEG relative molecular mass is 350, mass fraction is 30%) comb polymer is dissolved in 10g dry co-solvent CH 2 Cl 2 In, obtain the comb copolymer solution that mass fraction is 5 ‰;
[0041] (2) Measure 7.5ml of selective solvent ethanol, add the above-mentioned comb copolymer solution dropwise under stirring at room te...
Embodiment 2
[0049] A method for preparing a solid polymer electrolyte membrane material with continuous ion transfer nanochannels, the steps are as follows:
[0050] (1) Accurately weigh 0.05g PCOE-g-MPEG (MPEG relative molecular mass is 350, mass fraction is 30%) comb polymer is dissolved in 10g dry co-solvent CH 2 Cl 2 In, obtain the solution that mass fraction is 5 ‰;
[0051] (2) Measure 7.5ml of selective solvent ethanol, and add the above solution dropwise under stirring at room temperature, so that the final volume ratio of selective solvent to co-solvent is 1:1;
[0052] (3) Transfer the solution obtained in (2) into a dialysis bag with a molecular weight cut-off of 3500, and dialyze in a large amount of ethanol solution for 3 to 5 days, during which time the dialysate is replaced;
[0053] (4) After the dialysis is completed, fully shake the obtained micellar emulsion, add 0.010g of anhydrous lithium perchlorate to make [Li] / [EO] 1:4, and evaporate the solvent at room temperatu...
